The quality or state of being a fact; the certainty or reality of something being true or real.
From Latin 'factum' (a thing done, a fact) plus suffix '-tude' (state or quality). A relatively rare English word formed in the late 19th century following the pattern of words like 'magnitude' and 'gratitude'.
While 'factuality' is the common choice, 'factitude' survives in specialized writing about philosophy and reality—it has a more formal, almost Latin dignity. It's the kind of word that makes philosophers sound especially thoughtful.
